Abstract:
PURPOSE: The purpose of the present study is to evaluate the proximal metatarsal chevron osteotomy outcomes for moderate to severe hallux valgus more than seven year follow up. MATERIALS AND METHODS: Between 1996 and 1998, hallux valgus 61 cases were evaluated. The follow up period was more than seven years. The clinical review analyzed by the hallux metatarsophalangeal-interphalangeal scale of the American Orthopedic Foot and Ankle Society, radiologic review by the hallux valgus angle, first and second intermetatarsal angle. Complication also evaluated. RESULTS: Clinically, preoperative AOFAS score was average 43 points (range; 16~60 points) which significantly improved to 88 points (range; 61~100 points) at last follow up periods. Radiologically, the mean preoperative, postoperative, last follow up hallux valgus angle was 34 degrees, 5.2 degrees, 10.9 degrees. The mean preoperative, postoperative, last follow up intermetatarsal angle was 15.3 degrees, 3.3 degrees, 5.3 degrees. Postoperative angle change were no statistical significance (p>0.05). Complication were hallux varus 6 cases, metatarsophalangeal joint arthritis 2 cases, recurrence 1 case. CONCLUSION: Proximal metatarsal chevron osteotomy shows satisfactory outcome for moderate to severe hallux valgus more than seven year follow up.
